  2. Phenylbiguanide - Wikipedia

    en.wikipedia.org/wiki/Phenylbiguanide

    Phenylbiguanide (PBG) is a 5-HT3 agonist used to study the role of 5-HT3 receptors in the central nervous system. [1] It has been found to trigger dopamine release in the nucleus accumbens of rats. [2]

  3. Inductive effect - Wikipedia

    en.wikipedia.org/wiki/Inductive_effect

    In Organic chemistry, the inductive effect in a molecule is a local change in the electron density due to electron-withdrawing or electron-donating groups elsewhere in the molecule, resulting in a permanent dipole in a bond. [1] It is present in a σ (sigma) bond, unlike the electromeric effect which is present in a π (pi) bond.

  4. Biguanide - Wikipedia

    en.wikipedia.org/wiki/Biguanide

    Biguanide (/ b aɪ ˈ ɡ w ɒ n aɪ d /) is the organic compound with the formula HN(C(NH)NH 2) 2. It is a colorless solid that dissolves in water to give a highly basic solution. It is a colorless solid that dissolves in water to give a highly basic solution.

  5. Sigma bond - Wikipedia

    en.wikipedia.org/wiki/Sigma_bond

    There is no more than 1 sigma bond between any two atoms. Molecules with rings have additional sigma bonds, such as benzene rings, which have 6 C−C sigma bonds within the ring for 6 carbon atoms. The anthracene molecule, C 14 H 10, has three rings so that the rule gives the number of sigma bonds as 24 + 3 − 1 = 26. In this case there are 16 ...

  6. Chlorophenylbiguanide - Wikipedia

    en.wikipedia.org/wiki/Chlorophenylbiguanide

    meta-Chlorophenylbiguanide (1-(3-Chlorophenylbiguanide, m-CPBG) is an allosteric agonist and modulator of the 5-HT 3 receptor [1] [2] [3] and an antagonist of the α 2A-adrenergic receptor. [4] It has anxiogenic , emetic and hypothermic effects in animal studies.

  7. Pentagonal bipyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Pentagonal_bipyramidal...

    The pentagonal bipyramid is a case where bond angles surrounding an atom are not identical (see also trigonal bipyramidal molecular geometry). [1] [page needed] This is one of the three common shapes for heptacoordinate transition metal complexes, along with the capped octahedron and the capped trigonal prism. [2] [3] [page needed]

  8. Hydrazines - Wikipedia

    en.wikipedia.org/wiki/Hydrazines

    Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon groups. [1]

  9. Hydrosilanes - Wikipedia

    en.wikipedia.org/wiki/Hydrosilanes

    Hydrosilanes are tetravalent silicon compounds containing one or more Si-H bond. The parent hydrosilane is silane (SiH 4). Commonly, hydrosilane refers to organosilicon derivatives. Examples include phenylsilane (PhSiH 3) and triethoxysilane ((C 2 H 5 O) 3 SiH). Polymers and oligomers terminated with hydrosilanes are resins that are used to ...
